Abstract/OtherAbstract:
The transesterification of palm oil with methanol was investigated over calcium oxide catalysts prepared by calcining eggshells of quail and chicken. Compared to chicken eggshell, the palisade layer of quail eggshell had more closely dispersed micron-sized pores. Following treatment with 0.005M HCl solution for 2h to remove its dense cuticle layer and subsequent calcination above 800 degrees C, the quail eggshell had a large amount of strong basic sites and showed high catalytic activity comparable to that of potassium methoxide in the transesterification. The acid-treated, quail eggshell catalyst steadily maintained high conversions of over 98% during repeated fivefold usage at 65 degrees C with a reactant composed of methanol/oil (as mol)=12/1 and oil/catalyst (as g)=2/0.03.
